'Passion and excellence'

Rhodri Talfan Davies, director of BBC Cymru Wales, said the range of the nominations demonstrated the "passion and excellence" of the corporation's production teams, both in-house and across the independent sector.

"It is thrilling to see the BBC making a mark in English and Welsh, and in its output for both Wales and UK audiences," he added.

Allison Dowzell, interim director of Bafta in Wales, said: "This is a landmark year for Bafta Cymru and we have some exciting plans and a few surprises up our sleeve for this year's special event.

"What better way to celebrate our 21st birthday other than to recognise all the time, energy, determination and hard work that goes into making and producing creative media, TV and film programmes in Wales."
